Hi.
Thanks. I was on the right track with .choice()/.filter(), but just didn't know
how to figure out the right condition.
Just for anyone with similar problem. The IN message was an java.util.ArrayList
eg. the resultset from MyBatis. I used the .simple() language for the
condition. The route then became like this
from("timer://pollTheDatabase?delay=30000")
.to("mbatis:selectAllAccounts")
.filter().simple("${in.body.size} > 0")
.to("activemq:queue:allAccounts");
The .choice() did work too.
